Which company owns MAC address prefix 04:9D:FE?

MAC address prefix 04:9D:FE is registered to Hivesystem in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:9D:FE has a network interface built by Hivesystem.

What is the OUI 04:9D:FE?

04:9D:FE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hivesystem. It covers every address from 04:9D:FE:00:00:00 to 04:9D:FE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-9D-FE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:9D:FE:00:00:00 that is 04:9D:FE — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Hivesystem located?

Hivesystem is listed at 816 Kranz-techno Bldg. 388 dunchondaero, jun Gyeonggi-do KR KSXX0024 in the IEEE OUI registry entry for 04:9D:FE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
